The following four inflammatory factors were significantly associated with a reduced risk of infertility: caspase 8 levels (nSNP = 22, p = 0.006, OR = 0.841, CI = 0.743–0.952); C‐X‐C motif chemokine 5 (CXCL5) levels (nSNP = 21, p = 0.033, OR = 0.917, 95% CI = 0.846–0.993); interleukin‐18 levels (nSNP = 31, p = 0.024, OR = 0.900, 95% CI = 0.821–0.986); and leukemia inhibitory factor receptor (LIFR) levels (nSNP = 24, p = 0.019, OR = 0.885, CI = 0.799–0.980) (Supporting Information S3). Here, CXCL5 is linked to Infertility.
